Khushi Do Ghadi Ki (Door Ka Rahi) guitar chords and lyrics

This is a great slow ballad from the movie, Door Ka Rahi, in which Kishore Kumar acted himself. The original song has bare minimum music with some Rebab in intro and minor strumming (barely audible) in between verses.
My chords sound 100% accurate to me and are in the original scale. I've been listening to the song stop non-stop today so decided to put it up. Any comments/feedback is appreciated.
I hope to put my recording here soon.

These chords have to be fingerpicked (I do it Arpeggio style) for the song to sound in its spirit.
